I. RECALL and COMPREHENSION QUESTIONS
a. Define the chemical and physical change in your own words:
1. What is physical change?
A physical change is a change in which the form or appearance of a substance changes, but its chemical composition remains the same.
2. What is chemical change?
A chemical change is a change in which a substance transforms into one or more new substances with different chemical properties.
b. Identify and list two examples each of physical and chemical changes you observe in daily life (other than those discussed in class).
i. Physical changes: e.g.: melting ice and dissolving sugar in water.
ii. Chemical changes: e.g.: rusting of iron and baking a cake.
II. APPLICATION QUESTIONS
a. Why is melting ice considered a physical change?
Melting ice is a physical change because the ice (solid water) changes to liquid water without altering its chemical structure.
b. What makes the burning of paper a chemical change?
Burning paper is a chemical change because it reacts with oxygen to form ash, carbon dioxide, and other gases, resulting in new substances.
c. How can you tell if a new substance has been formed during a change?
You can identify a new substance by observing changes in color, temperature, formation of gas bubbles, or the development of a precipitate.
III. ANALYSIS QUESTIONS (thinking critically-inferring from the observation)
a. What observation during the candle experiment indicates a chemical change?
The formation of soot or changes in the wax's color suggests a chemical change during the candle burning.
b. Which part of the candle experiment showed physical change, and how do you know?
The melting of the candle wax is a physical change, as the wax changes state from solid to liquid without creating a new substance.
IV. EVALUATION QUESTION
How would you respond if someone claimed all changes in matter are chemical changes?
I would explain that not all changes in matter are chemical; many changes, like melting or freezing, are physical changes where the substance remains the same chemically.
HOMEWORK
Design simple home experiments that demonstrate both physical and chemical change?
1. **Physical change experiment**: Freeze water in an ice tray and then let it melt to show how the state changes from solid to liquid.
2. **Chemical change experiment**: Mix baking soda and vinegar in a bowl to observe the fizzing reaction, which produces carbon dioxide gas and results in new substances.
